WAVE-MOTOR.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed April 26. 1907 $erial No. 370.413.

To all whom it may concern:

Be it known that I, DAVID BINNs, citizen of the United States, residingat Camp Chase, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Wave-Motors, of whichthe following is a specification.

My invention relates to neW- and useful improvements in wave-motors.

The object of my invention primarily, is to provide a wave motor of thepump type, and in carrying out the invention to employ the piston notonly as a piston, but as a conductor for the water.

Another feature resides in the fact that an extremely long piston ormast and anelon-' gated pumping barrel. or casing is used. With thisconstruction the motor readily adjusts itself to high, low andintermediate tides.

Finally the invention has relation to the production of a wave motor ofsimple and inexpensive construction as well as great efficiency andstrength and comprising comparatively few parts, thus reducing theexpense of operation and the liability of the parts getting out ofworking order, to a minimum.

With the above and other objects in view, the invention consists of thenovel details of construction and operation, a preferable embodiment ofwhich is described in the specification and illustrated in theaccompanying drawings, wherein:

Figure 1 is a vertical sectional view broken away in places 011 accountof the extreme length and showing a portion of the supporting structurein elevation. Fig. 2 is a horizontal cross section taken on the line y-yof Fig. 1, and Fig. 3 is a horizontal cross section taken on the linex-9c of Fig. 1 and showing a portion of the float or buoy.

In the drawings the numeral 1, designates an elongated cylindricalcasing or barrel carrying at its upper end a suitable packing box 2. Atits lower end, the barrel is screw threaded or otherwise secured to astrainer casting 3. The lower end of the casting is rounded and formedinto a suitable strainer 4, while nearer the upper end a transversedconical valve seat 5 is formed and receives .an ordinary conical valve6. Above the valve a horizontal guard and guide 7 receives the valvestem in the usual manner and limits the upward movement of the valve.Immediately or a short distance above the casting 3 a rounded ring 8 isformed integral with or suitably fixed on the barrel 1. as shown inFig. 1. This ring receives a suitable buoy or float 9, the same beingshaped to fit snugly on the ring so that a ball and socket joint is had,and the float allowed to swing in various directions so as toaccommodate itself to the surface of the water and the action of thewaves. While I have shown the float 9 as a solid body circular in shape,it is to be understood that the same may be of any desired shape andconstruction. However, in accordance with my invention the inlet of thebarrel 1 must be below the upper surface of the float and I prefer tohave the same on a line with the under surface or a short distance belowthe same. It is obvious that the inlet end of the barrel should alwaysbe submerged.

The barrel loosely receives. a hollow piston 10 which enters through thepacking box 2 and projects some distance down into the barrel, the jointat the packing box of course being water tight. It is obvious that bythis arrangement the barrel is afforded an unlimited vertical movementon the piston so that at the different tides the barrel will merely workhigher or lower on the piston.

One of the essential features of this inven tion lies in the use of ahollow piston acting to conduct the water, in the pumping of which itassists. Another essential feature resides in rigidly supporting thispiston against longitudinal movement and in the drawings I have shown abeam 11 forming part of a pier or other fixed support and I wish itunderstood that this support must be fixed so as not to be effected bythe waves or tide. I have shown the piston secured to the beam 11 by astrap 12, however it may be secured in any desirable way.

The upper end of the piston projects above the beam and is screwthreaded or otherwise secured in the lower end of a valve sleeve 14having a transverse conical valve seat 15 receiving a conical valve 16,the stem of which engages in a guard and guide 17 like the guard 7. Thissleeve receives an elbow 18 which acts to hold the guard 17 in lace andreceives at its opposite end, a suitab e off-bearing pipe 19. It is tobe understood that the piston 10 may project some distance above thebeam 1 1 and that its length may be varied in accordance with thecircumstances.

A short distance above the float 9 a looped ring 20 is secured to thebarrel in any suitable way. At four equidistant points the ring carriesswivels 21 to which the ends of radiating cables orother flexibleconnections 22 are secured. These cables should be of some length andsecured at their outer ends to fixed parts. By the use of these cablesthe barrel is allowed a free up and down movement but is held againsttwisting and undue lateral or swinging movement.

As before. stated by the use of an elongated barrel and piston the motorreadily accommodates itself to the various tides. To further illustratethis I have shown the position of the parts at high tide in full linesin Fig. 1 and the position at low tide in dotted lines.

The operation of the motor is as follows. When the float 9 carries thebarrel 1 down, the-valve 16 would be closed owing to the suction ofvacuum created and the valve 6 o ened permitting water to be drawn in trough the strainer 4 into the barrel 1 and piston 10 above valve 6. Asthe float carries the barrel upward, the valve 6 closes and the water'isforced up through the piston, unseating the valve 16 and passing throughthe elbow 18 to the off-bearing pipe 19 from which it may be conveyed tothe desired point. In this way a great quantity of water may be elevatedand stored or used for any purpose desired.

It is to be noted that there is comparatively little or no wear upon theparts, as the piston fits loosely in the barrel, all the wear beingtaken by the packing box. By employing the hollow piston as a conductor,an eflicient, simple and inexpensive device is not only provided but theuse of flexible connections and numerous packed joints are avoided. Alsoa dlrect acting water elevator of great capacity operating under varioustide condit1ons is provided.- By fixing the hollow piston againstlongitudinal movementa steady action is assured, which would not beobtained if the motor was held from a movable urchasepoint; also byusing the hollow piston to conduct the water the barrel may be madequite small in tion to the elevating capacity.

What I claim is: 1. In a wave motor, the combination with a float and afixed su port above the float, of a barrel carrying the loat and havingits inlet end below the surface of the float, and a holproporlow pistonadapted to convey water fitting in the barrel above the float and heldagainst longitudinal movement by thefixed sup ort.

2. In a wave motor, a float, a barre attached to the float, a valvearranged in the barrel, a hollow iston fitting loosely in the barrelabove the float and adapted to convey water, said piston being heldagainst longi tudinal movement, and a valve carried by said piston.

3. In a wave motor, a float, a barrel attached to the float, a valvearranged in the barrel, a hollow piston fitting loosely in the barrelabove the float and adapted to convey water, said piston being heldagainst longitudinal movement, a valve carried by said piston, andnon-flexible means connected directly to the piston for'conveying thewater conveyed thereby.

4. In a wave motor, a float, an elongated barrel attached to float andhaving the inlet end below the surface of the float, an elongatedhollow'piston fitting loosely in the barrel'having its lower endterminating above the float, a valve working above the inlet end of thepiston, and a fixed support having connection with the piston arrangedto hold the latter against longitudinal movement.

5. In a wave motor, a fixed hollow piston, a barrel receiving saidpiston and working thereon, a float attached to the barrel, and guidingmeans for the float radiating from the barrel a short distance above thefloat.

6. In a wave motor, a float, a barrel extending above and below thefloat and having its inlet end below the float, a valve arranged in theinlet end of the barrel, and a fixed hollow piston adapted to conveywater from the barrel and telescoping into the barrel above the float.

7. In a wave motor, a float, a barrel extending above and below thefloat and having its inlet end below the float, a valve arranged in theinlet end of the barrel, a fixed hollow piston adapted to convey thewater from the barrel and telescoping into the barrel above the float,and a valve associated with the piston.

In testimony whereof I aflix my signature in presence of two witnesses.

DAVID BINNS.
